VEHICLE-J ACK.

To all whom t may concern.'

Be it known that I, WILLIAM M. I'IA'YNIE, a citizen of the UnitedStates, residing at Newnan, in the county of Coweta and State ofGeorgia, have invented certain new and useful Improvements inVehicle-Jacks, of which the following is aspeciication, ref erence beinghad therein to the accompanying drawings.

The invention relates to an improved vehicle jack and more particularlyto a device of this nature especially adapted and useful in elevatingand supporting automobiles to remove the weight from the tires when theautomobiles are stored and for other pui'- poses.

An object of the invention is to provide an improved device of thisnature of very simple and inexpensive construction that will be strongand eiiicient in use.

The invention broadly comprehends a vehicle supporting frame with pairs.of elevating and supporting levers connected to the frame and adaptedto be swung or rocked to vertically adjust the vehicle supporting frame,and a further object of the invention is to provide improved manuallyoperable mechanism to rock the levers for raising and lowering thevehicle supporting frame, and for maintaining the vehicle frame in 4itselevated position.

A further object of the invention is the provision of improved manuallyoperable mechanism providing for the rocking of the elevating andsupporting levers to effect a gradual lifting of the frame and tlie'easymanual operation of the device in handling heavy weights, and alsoproviding for the quick adjustment orraising and lowering of the vehiclesupporting* frame in dealing with the lighter weight vehicles.

The invention, with other objects and advantages thereof and theparticular construction, combinations and arrangement of partscomprising the same, will be understood from the hereinafter containeddetail description, when considered in connection with theaccompanying.drawings, forming part hereof, and illustrating a preferredembodiment of the invention.

sition of the frame and the elevating and supporting levers beingindicated in dotted lines.

Fig. 2 is a top plan view of the forward portion of the device.

Fig. 3 is a section taken on the line 3--3 of Fig. 1,

Fig. 4; is a section taken on the line 4.-4; of Fig. 2.

Fig. 5 is a detail view of part of the vehicle supporting frame.

In the drawings, I have illustrated, by way of example, a particularembodiment of the invention but it will be understood that variationsand minor changes of the particular construction shown, as will appealto those skilled in the art, may be made without departing from thebroad principles of the invention.

rI`he particular construction illustratedrin the drawings comprises abase or supporting bed composed of two longitudinal sills or memberseach of which is made up of two beams 1 1 of angle iron arranged side byside with their ianges 2 2 vertically dis posed adjacent each other, andtheir flanges 3-3 extending horizontally providing bearing surfaces. Thebeams 1 1 of each of the longitudinal sills or members are spaced aslight distance apart by blocks 4, and the parts are rigidly fastenedtogether by front and rear transverse tie rods 5 and nuts 6, the ends ofthe tie rods extending through openings in the vertical iianges 2-2 ofthe beam 1-1. 7 designates an additional transverse brace member' ofangle iron suitablyr secured to the longitudinal members near the frontend of the base.

' The vehicle supporting frame consists of two longitudinal members eachmade up of a pair of metal beams 8--8 and having aXle engaging seatymembers 8a at their outer ends. 9 designates spacing blocks between thebeams 8-8 of each longitudinal member,

and the longitudinal members are rigidly secured together by front andrear transverse tie rods-lO-IO'and nuts 11, the ends of the tie rodsextending through suitable openings in the beams. The tie rods 10 intermediate their endsv are preferably bowed or curved downwardly, and thebeams 8-8 are also depressed intermediate their ends, as shown, toprovide clearance for the underframing and the connected mechanism ofautomobiles so that the Vmembers 8a on the straight end portions of thebeams @3e-8 can vated position.

be freely engaged with the front and rear saxles of the automobile. Y

1-2 designates levers for elevating and' supporting n the vehicle frame.`The levers. 12 are arranged in pairs and pivotally connectedat oppositeends with the base and ver members'of the base and vehicle supportingframe, the tie rods serving as pivots for the levers. Guide frames areprovidedl for lthe "pair of levers at the front end of the sup# Eachguide frame consists porting frame. of a pair of curved bars13 rigidlysecured at'their end portions to one ofthe longitudinal members of thebase opposite to each other and in spaced relation to permit the leversto operate therebetween. An advantageous connection of the curved guidebars with theibase is obtained by offsetting the end' portions of thebars 13 inwardly and securing the same `together by rivets or the liketothe angle beams l in the spaces thcrebetween.

I fThe-levers 12 are adapted,r to be rocked fromlthe position indicatedin dotted lines in Fig'. l of the drawings to elevate and support thevehicle frame" in the position indicated'in full lines in Fig. 1 to liftan automobile from the grou-ndr and support the same to remove theweightl of the vehicle from the tires thereof for storing purposes or inthe case of overhauling or repair work, the motor vehicle being adaptedto be positioned above the vehicle frame so that the straight endportions ofthe vehicle supporting frame will engage the axles of thevehicle and elevate and support the vehicle when the vehicle Vframe israised to its ele- @n the guide frames Vvare stopsI 14 ari ranged to beengaged by the forward pair of so 'provided Vfor rocking the levers 12to raise f levers when they are swung to an up-right gposition. VStops15 are also provided to limitthe downward movement of the levers.

The stops 14: and 15 are each formed by av block 1G secured between thecurvedy bars 13 Vof'the guide frames, said curvedbars being provided`with oppositely disposed outwardlyoffset portions forming pockets inwhichl the stop blocks are' secured byV rivets orthe like."` f

'i A particular'important novel feature of the invention reside's'inlthe'special Vmeans and lower' the vehicle supporting frame.-

' The improved mechanism Vfor this purpose comprises a shaft'l? mountedfor-rotation at the front of thebase, said shaft extending transverselyof the base, the ends of the shafts engaging suitable bearings providedon the longitudinal members 1 of the base. On the shaft 17 are two crankarms 19 located near opposite sides of the base, the cranks beingdisposed parallel to each other. Pivotal link connections 20 areprovided between the outer ends of the crank arms 19 and the ends of thelongitudinal members of the vehicle supporting frame. The cranks andlevers are so proportioned that when the elevating and supporting levers12 occupy an up-right posi-tion the cranks extend in longitudinalalinement with the links 20, the construction providing in thisparticular, locking means for maintaining the vehicle support-ing framein its elevated position. Keyed to the shaft is a ratchet wheel 21, and22 is a lever rotatably engaging the shaft at one end and held inposition adjacent the ratchet wheel in any suitable manner for instance,by a collar 23. Pivotally mounted on the lever a pawl Z-t adapted whenthe lever is oseillatod in a forward direction to coperate with the'atchet wheel 21, to rotate the shaft. 25 designates a gravity pawl forthe ratchet wheel, said pawl being pivotally mounted on the forwardtransverse angle member 7. The ends of the shaft project a shortdistance from opposite sides of the base and iixedly secured thereto areoperating levers Q6.

It will be observed that this construction provides for a graduallifting of the frame and the easy manual operation of the device inhandling heavy weights, this being effected through the pawl and ratchetlocated centrally of the shaft, and also that provision vis made for thequick adjustment or raising and lowering of the frame through theoperating levers 2G that are ixedly secured tothe ends of the shaft.

It will also be noted that the special construction of the base orsupporting bed, the vehicle supporting frame and the particular locationand connection of the elevating and supporting levers provide a verysimple and strong construction which can be manufactured at littleexpense.
